The Alvis Car and Engineering Company was a British manufacturing company that produced automobiles, racing cars, aircraft engines, and military vehicles from 1919 to 1967 in Coventry. The company had a reputation for producing high-quality luxury cars, including the Alvis Speed 20 and the Alvis 4.3 Litre, and also built armored cars and military vehicles such as the Saladin armored car and Stalwart amphibious truck. In 1965, the company became a subsidiary of Rover and car manufacturing stopped, but Alvis continued to make armored vehicles. Alvis was later sold to United Scientific Holdings in 1982, which renamed itself Alvis plc.
